Chromosome Mutations and pH Disturbances

Abstract
Chromosomal anomalies, namely hypodiploidies, hyperdiploidies, and endoreduplications, developed in nearly 25% of metaphase plates of replicating human lymphocytes exposed in vitro to either acid (6.5 to 6.9) or alkaline (8.4 to 8.8) pH equilibriums. The G group was most susceptible to aneuploid formation. Mammalian mutations may develop as the result of a pH disturbance during cleavage of the fertilized zygote.
